Couple of comments from Down Under..
1. looks like ~5A fuse
2. 150 Ohm 1% 3-5W resistor

Is that 150 Ohm resistor part of an attenuator?
What value are the two standing vertical?
Are they factory or an after thought by previous owners?

Skipp and Carl,

That board looks very much like a lot of the first-stage/driver boards I have seen in the higher-power amplifiers.  A lot of the TPL amps were just combinations of the same few stock boards with different component values used for different bands and drive levels.  If I can find some pictures of the amps I have (I am on the road) I will share them for comparison.  The label almost looks like it says 80W in 60W out but that must be 8.0W in 60W out.  I assume you confirmed that the failure is actually a failed power transistor not another component failure or cold solder joints.  Is it open or shorted?

Thanks,

Re: #cdm #cdm1250 CDM AAM25SH works ar 443MHz? #cdm #cdm1250

Dan Woodie
 

Duane, 

There are ways CDMs can be programmed out of band, however when you move significantly outside the factory band split you are beyond the calibration points so performance cannot be guaranteed and power out will likely be decreased (or could go high, exceeding the rating of the finals).

The CDM mobiles have gotten so cheap that finding a 403-470 split unit at a reasonable price should be easy.  If you only need one or two channels for use as a control receiver, etc then a CDM750 would be more than enough radio.  Same radio with a simpler control head.

You might be able to get more for the radio you have selling it to someone for commercial service that it may cost to purchase a low-UHF CDM.

While the challenge of such a mod is enticing unless you are specifically looking for said challenge and willing to risk bricking the radio and/or ending up with poor performance with the current market conditions for that model picking up a different unit is probably your best option. 

Thanks,

Neal,

Is the crystal for the receiver cut for high-side local oscillator injection?  If not, you've got some work to do.  Retuning can be difficult at best, and you probably won't end up with very good sensitivity when you do get it tuned.

Re: M2 PLL VHF exciter output power High?

 

Yup - there's noting wrong here...  I'd say the power is closer to 650 - 750 mW and the meter you're using is a little generous.

There's nothing wrong here.

Objet : Re: [repeater-builder] TPL Amplifier model 3010

 

Skipp, 

 

I was kind of suspecting the same thing about TPL being out of business but I hadn't seen anyone talking about it.  It seems they just kind of vanished.

 

I can guess that one of several reasons was lack of quality control.  A few years ago I picked up a handful of VHF 75W in 250W out TPL amps that were NOS.  The first one worked just fine and I was able to optimize it for the frequency where I would be using it.  When I opened up the second one to start the same process to tune it up as a spare I found that though the boards were installed in an identical manner the cabling was a bit wonky in the second one.  After some side-by-side comparison I determined that the gozinta and gozouta (technical terms) on the RF Sense/matching board were cabled in reverse which means the amp would never key on RF Sense because the input power would not be passed to the RF sense circuit.  I carefully re-routed the cabling and made it identical to the first unit and was able to get it working to factory specs.

 

So that makes you wonder how it passed the QC checks before shipping, doesn't it?

 

Unfortunately for all of their troubles TE actually made decent amplifiers that were easy to work on.  TE Systems are great also but I have seen my share of failures with those as well.  Crescend amps work well as long as you drive them with the EXACT power and frequency they are designed for and keep a low VSWR on the output at all times.  Unfortunately Crescend is not all that friendly to hams unless you are going to buy a new amp at full retail.

 

All of this does bring up a point (which is not necessarily aimed at this particular thread).  It seems like folks are obsessed with running lots of power.  The problem with that is although the numbers seem big remember that for every doubling of power it only gives you 3 dB of OUTBOUND gain while likely effectively decreasing your INBOUND gain by raising the noise floor due to desense or wideband noise caused by PIM or other sources.  The more power you run the harder it is on everything in your signal chain and you have to make sure everything is rated for the increased power.  A much more effective way to increase your coverage is to use antenna gain or better heliax to decrease feedline losses (which can help inbound and outbound signals by changing one run of coax or one antenna if running duplex on a single antenna).

 

The TPL 3010 that is part of this discussion is not really applicable to this since it is a low-drive mid-power amp.

 

As far as finding transistors for that amp I would contact RF Parts.  They seem to have some pretty good cross-references and even if they don't have the parts you need they might be able to send you down the path to what you need.

 

Thanks,

Hello Carl (and the Group)....  Carl, until now I haven't written much about
your amplifier information request because the answer can get quite involved
and time consuming. But since you've been so sincerely working hard on your
repeater and link project... I'll be happy to try and help you with some information
and silly jokes.

TPL made a lot of amplfiiers through the decades they were in business. I
suspect they are now out of business, but that's another thread to later talk
about. Some of the Group Members have a lot experience with RF Amplfiers,
a number of those members chat in direct Emails because they don't want to fill
up the group with more than the normal noise (talk).  We do have some RF
Amplifier archives that are not (yet) available on line (that I know about), but
they could be made available if someone needed a related diagram.

A well informed friend once told me the story of the SRF transistor part numbers,
I could ask him again about it, but it's not that important really. The SRF RF
transistor part numbers were a "house" or specific source (or supply) that were
provided by Motorola (I believe)... many decades back. There have been MRF and
SRF cross reference tables listed in some data books, sometimes even those number
and cross lists are not exact or complete for all the devices made.

Many TPL RF Amplifiers are pretty generic and the older ones do follow common PC
board, circuit design, layout, construction and popular part values for the era of when
the amplifier was made.  Even with a basic amplifier, there were a fair amount of
different options that were offered... Transmit/Receive Switching Relays, Diode TR
Switching, Linear Operation (bias the transistor for AB operation) and the traditional
Class-C FM (and some digital) modes.

Circuit layout wise, you can have a single transistor "device" or "single stage" amplfier, then
two or more devices in series, parallel, then series-parallel combinations and some
rather interesting power combiner / distribution systems (networks). TPL combined
RF amplifier power both on the PC board traces, through hybrids and through a
network I forget the name of... Jeff likes that particular combiner and can probably
better provide the label and a description for it.  There are also single and multiple
device amplifiers in a modular or "pallet" for construction style.

So, probably the best thing to now do, is to take a few very well lighted inside views
of your amplifier, showing the circuit board layout... Then post those pictures here
(or Email them direct to me) and I'll tell you all about the amplifier, probably come up
with some very usable information, a similar or same schematic... or something that
will work fine for repairing your amplifier.  Coming up with a workable transistor part number
shouldn't be that big of a deal, I might even locate one I could send you (not promising
anything fast or for sure).  One member of Junk Enders 12 Step Program, Left Coast
Division was a long time TPL RF Amplifier Service Station, so there's probably not a
lot of models he/she/stray-cats hasn't seen up close.

Get us some pictures... we'll get your car push started..

If you're talking about the original large blue-box micro-processor based version, I believe it is/was
a 6502 (based) chipset.  There are actually a ton of resources around for learning, developing and using
older 6502, 6800/6803/6809, Z80 & 8085 micro controller systems.  if you really wanted to have some
older small controller fun... there's a Groups I/O (group) for the original Heathkit ET-3400 micro
processor trainer. It's got enough simple input / output "I/O", that you could easily experiment with
making up your own repeater controller interface and developing the operating system on the
fly.

There have been an impressive number of small micro-processor (and pic based) repeater
controllers offered through the years. Working with a very limited amount of RAM and other
hardware resources, requires some creative and impressive code (programming) skills. 

Back to the Kendercom unit... when I last repaired one...  Jameco had a decent supply of the
chips in the 6502 family... although that's probably different now because it's been a while.

"Been a while"
